Ensure increased reliability with ARINC 429 IP Core for FPGA

DO-254 compliant offering with multichannel ARINC 429 transmitter/receiver core Overview Cyient IP Core Features

ARINC 429 specification defines the standard • Developed according to DO-254 (DAL-A) requirements for the transfer of engineering data guidelines between systems on commercial aircraft • Two transmitters and eight receivers with supporting high speeds of up to 100 kHz as well loopback mode for self -testing as speeds as low as 12.5 kHz. The ARINC protocol • Portable to Microsemi, Intel/Altera, Lattice, or supports more than 46 meters. Xilinx FPGA families The Cyient ARINC 429 IP Core is developed for • Supports standard line drivers and receivers FPGA with multiple transmitters and receivers and • Parity checking for Tx and Rx is compliant with Design Assurance Level (DAL) • Programmable labels (up to eight different labels) A requirements. It receives data from an external • Programmable label filtering and SDI check microcontroller through SPI lines and transmits • SPI interface to the microcontroller 32-bit data word (encoded serial data) through the ARINC line driver. ARINC429 IP Core receives • Programmable data rates for each channel: 12.5 serial data from the ARINC line receiver and or 100 kbps transmits 32-bit decoded data word to an external • Detection of parity, label, SDI, and data errors microcontroller.
